Which organization established the lead content regulations in paint?

The correct choice is the Consumer Product Safety Commission (CPSC), which established regulations regarding lead content in paint. The CPSC's regulations stem from the intent to protect the public, particularly young children, from health hazards associated with lead exposure, which can occur through various products, including paint.

The CPSC recognized lead's toxicity and its significant risk to children due to lead-based paint, especially in homes built before the federal ban in 1978. To mitigate these risks, the CPSC set specific limits on the permissible levels of lead in paint, ensuring that consumer products are safe and that manufacturers are held to these standards.

Understanding the role of the CPSC in this context highlights the importance of consumer safety regulations and the agency's responsibility for overseeing products that could potentially harm public health.
